4 1.0 Introduction 1.1 Combined Sewer Overflows (CSOs) Like many older cities in the United States, the sewer system in the District is comprised of both combined sewers and separate sanitary sewers. A combined sewer carries both sewage and runoff from storms. Modern practice is to build separate sewers for sewage and stormwater, and no new combined sewers have been built in the District since the early 1900's. Approximately one-third of the District (12,478 acres) is served by combined sewers. The majority of the area served by combined sewers is in the older developed sections of the District. In the combined sewer system, sewage from homes and businesses during dry weather conditions is conveyed to the District of Columbia s Blue Plains Advanced Wastewater Treatment Plant (Blue Plains), which is located in the southwestern part of the District on the east bank of the Potomac River. There the wastewater is treated to remove pollutants before being discharged to the Potomac River. When the capacity of a combined sewer is exceeded during storm events, the excess flow, which is a mixture of sewage and stormwater runoff, is discharged to the Anacostia and Potomac Rivers, in addition to Rock Creek and tributary waters through outfalls. This excess discharge during storm events is called a combined sewer overflow, or CSO. A total of 53 CSO outfalls are listed in DC Water s National Pollutant Discharge Elimination System (NPDES) Permit issued by the United States Environmental Protection Agency (EPA). DC Water is moving forward with the design and construction of a tunnel system in the Anacostia watershed to capture, store and convey combined sewer flows to Blue Plains in accordance with a 2005 federal Consent Decree. DC Water now proposes to expand its commitment to Green Infrastructure (GI) and has invested significant resources and engaged a broad group of stakeholders to prepare a draft Green Infrastructure Project Plan (GI Project Plan). 1.2 DC Clean Rivers (DCCR) Project Communities with combined sewer systems are required to prepare Long Term Control Plans (LTCPs) for the control of CSOs in accordance with Section 402(q) of the Clean Water Act. DC Water s LTCP was completed in July 2002 and is currently being implemented through the DC Clean Rivers (DCCR) Project. The DCCR Project is comprised of a system of tunnels for the Anacostia River, Rock Creek, Piney Branch and the Potomac River that will capture combined sewer flows for treatment at Blue Plains. The schedule for completing the Project is included in a Federal Court Consent Decree between the United States, the District Government and DC Water. 1.3 Green Infrastructure Project Plan The GI Project Plan considers innovative solutions that could substantially change the approach taken on the planned Potomac and Rock Creek tunnel projects outlined in the Consent Decree. As the steward of rate payer dollars, DC Water ensures the best return on its water quality investment. 1-1

5 The use of GI could provide benefits beyond improving water quality, including improved air quality, reduced urban temperatures and energy demand, and reduced flooding. It can also provide community benefits such as local job creation, improved property values and recreational areas. The GI Project Plan advances DC Water s proposal to conduct a large-scale, multi-million dollar demonstration project in the Potomac and Rock Creek watersheds for the purpose of evaluating the practicality and efficacy of implementing GI for the control of CSOs in these watersheds. The GI Project Plan proposes a comprehensive approach to the demonstration project, including GI site selection, identification and resolution of institutional issues and obstacles, public outreach, design and construction, monitoring and evaluation, and the preparation of a series of technical memoranda that detail every aspect of the demonstration project. Following completion of the demonstration project, as informed by a preliminary screening analysis, DC Water proposes to use the project s findings to conduct an analysis of alternative green and green/gray infrastructure controls with the goal of identifying alternative solutions for each of the two watersheds. Compared to present plans laid out in the Consent Decree, this would be consistent with the CSO Control Policy, be potentially more sustainable, and be capable of yielding a range of additional benefits to the community. 1-2

6 2.0 Green Infrastructure Challenge 2.1 Goals As part of a recent partnership agreement, DC Water will join forces with the US EPA and the District to collaborate on efforts that will be of critical importance to the success of the GI Project Plan. One of those efforts is implementing a Green Infrastructure Challenge (or GI Challenge ) that will engage the design community to construct innovative, practical green infrastructure solutions in the District. The focus of the Challenge will be on the following goals: 1. Advancing innovative GI technologies in retrofit applications in the urban environment for CSO control with the goal of increasing runoff capture from impervious surfaces and reducing the associated costs of such retrofits; 2. Illustrating practicality by showing what is feasible, and developing actual projects that will later be constructed in each area/design category; and 3. Accelerating the implementation of innovative GI technologies that will support the development of DC Water s demonstration project. 2.2 Categories Each design team must choose one of the following categories for which to submit an entry: Public Space; Commercial and Private Property; or Governmental and Institutional. Design concepts are limited to the Potomac and Rock Creek sewersheds (see Section 3.2) Public Space Over half of the impervious area in the sewersheds is public right-of-way (ROW), offering great potential to eliminate runoff into the combined sewers. Entries in this category are limited to ROW areas, including roadways, sidewalks, and alleys. Design teams must choose one of two subcategories for Public Space: 1. Any location within the Public ROW of the Potomac or Rock Creek sewershed boundary (see Section 3.2). 2. One of the two identified locations within the Public ROW (see Section 3.2). Commercial and Private Property Private property in the sewershed areas makes up 40 percent of the impervious area. Implementing green infrastructure in these areas is critical to overall CSO reduction goals. Entries in this category are limited to retrofitting existing properties (as redevelopment may complicate permitting issues) in either the Potomac or Rock Creek sewersheds (see Section 3.2). Design teams are encouraged to consider neighborhood enhancements and should demonstrate collaboration with community organizations in GI implementation and O&M agreements. Governmental and Institutional The District has a large number of Governmental and Institutional sites and buildings. The impervious surface in this category makes up nearly 10 percent of the total. Entries in this category 2-1

7 are limited to government and institutional properties, including Federal, Schools, District, and Nonprofit properties in either the Potomac or Rock Creek sewersheds (see Section 3.2). Design teams are encouraged to consider collaborative and educational opportunities with institutions. 2.3 General Procedures and Requirements Team Eligibility Each entry must come from an integrated design team consisting of at least one Professional Engineer (with ability to obtain registration in District of Columbia, if awarded) and one Registered Landscape Architect. Multidisciplinary teams are strongly encouraged to promote creativity and innovation. See the Terms and Conditions section for team eligibility restrictions. Submission Criteria All entries must be uploaded to no later than October 1, 2013 at 5:00 pm EDT.
